TRANSAXLE MAINTENANCE
The transmission fan and cooling fins should be kept clean
to ensure proper cooling.
Do not attempt to clean fan or transmission while engine
is running or while the transmission is hot. To prevent pos-
si ble damage to seals, do not use high pressure water or
steam to clean transmission.
•
Inspect cooling fan to be sure fan blades are intact and
clean.
•
Inspect cooling fins for dirt, grass clippings and other
materials. To prevent damage to seals, do not use com-
pressed air or high pressure sprayer to clean cool ing fins.
TRANSAXLE PUMP FLUID
The transaxle was sealed at the factory and fluid main te-
nance is not required for the life of the transaxle. Should
the transaxle ever leak or require servicing, contact your
near est au tho rized ser vice center/department.
ENGINE
LUBRICATION
Only use high quality detergent oil rated with API service clas-
sification SG-SL. Select the oil's SAE viscosity grade accord-
ing to your expected operating temperature. When operating
in temperatures below 0º F (-18º C) syn thet ic oil must be used.

TEMPERATURE RANGE ANTICIPATED BEFORE NEXT OIL CHANGE
* CAUTION: Air cooled engines run hotter than au to mo-
tive engines. The use of non-synthetic multi-viscosity oils
(5W30, 10W30 etc.) in temperatures above 40º F (4º C)
will result in higher than normal oil consumption. When
using a multi-viscosity oil, check oil level more frequently.
** CAUTION: SAE 30 oil, if used below 40º F (4º C), will
result in hard starting and possible engine bore damage
due to inadequate lubrication.
NOTE: Synthetic oil meeting ILSAC GF-2, API
certification mark and API service symbol (shown
SAE
5W-30
at left) with "SJ/CF ENERGY CON SERV ING" or
higher, is an acceptable oil at all temperatures.
Use of synthetic oil does not alter required

oil change intervals.
ENGINES
Change the oil after every 50 hours of operation or at least
once a year if the tractor is not used for 50 hours in one year.
Check the crankcase oil level before starting the engine
and after each eight (8) hours of operation. Tighten oil fill
cap/dipstick securely each time you check the oil level.
TO CHANGE ENGINE OIL (See Fig. 17)
Determine temperature range expected before oil change.
All oil must meet API service classification SG-SL.
•
Be sure tractor is on level surface.
•
Oil will drain more freely when warm.
•
Catch oil in a suitable container.

•
Remove oil fill cap/dipstick. Be careful not to allow dirt
to enter the engine when changing oil.
•
Remove yellow cap from end of drain valve and install
the drain tube onto the fitting.
•
Unlock drain valve by pushing inward and turning
coun ter clock wise.
•
To open, pull out on the drain valve.
•
After oil has drained completely, close and lock the
drain valve by pushing inward and turning clockwise
until the pin is in the locked position as shown.
•
Remove the drain tube and replace the cap onto to the
bottom fitting of the drain valve.
•
Refill engine with oil through oil fill dipstick tube. Pour
slowly. Do not overfill. For approximate capacity see
"PRODUCT SPECIFICATIONS" section of this man u al.
•
Use gauge on oil fill cap/dipstick for checking level.
Insert dipstick into the tube and rest the oil fill cap on
the tube. Do not thread the cap onto the tube when
taking reading. Keep oil at "FULL " line on dipstick.
Tighten cap onto the tube securely when finished.

ENGINE OIL FILTER
Replace the engine oil filter every season or every other
oil change if the tractor is used more than 100 hours in
one year.
AIR FILTER
Your engine will not run properly using a dirty air filter.
Service air cleaner more often under dusty conditions.
See engine manual.
CLEAN AIR SCREEN
Air screen must be kept free of dirt and chaff to prevent
engine dam age from overheating. Clean with a wire brush or
compressed air to re move dirt and stubborn dried gum fibers.
ENGINE COOLING SYSTEM
To ensure proper cooling, make sure the grass screen,
cooling fins, and other external surfaces of the engine are
kept clean at all times.
Every 100 hours of operation (more often under extremely
dusty, dirty conditions), remove the blower housing and other
cooling shrouds. Clean the cooling fins and external surfaces
as necessary. Ensure the cooling shrouds are reinstalled.
NOTE: Operating the engine with a blocked grass screen,
dirty or plugged cooling fins, and/or cooling shrouds re moved
will cause engine damage due to overheating.
MUFFLER
Inspect and replace corroded muffler and spark arrester (if
equipped) as it could create a fire hazard and/or damage.
